Full details
The Varta Longlife 2100mAh Rechargeable AA battery is an ideal choice for users seeking a reliable, high-capacity power source for standard household electronics. Designed with NiMH technology, these batteries offer the convenience of low self-discharge, retaining 80% of their charge after one year, though they are specifically engineered for devices requiring a 1.2V nominal voltage rather than high-drain specialized equipment.

FAQs
Can I use these in any device that takes AA batteries?
Yes, they fit standard AA compartments, but be aware they are 1.2V. Most devices designed for alkaline batteries handle 1.2V perfectly well.
Do I need a special Varta charger?
No, you can use any standard, high-quality NiMH battery charger.
How long do these batteries last?
The lifespan depends on usage and charging habits, but NiMH batteries typically handle hundreds of charge cycles before performance degrades.
What is the weight of one battery?
Each battery weighs approximately 26g.
Are these batteries pre-charged?
Varta Ready2Use batteries are designed to be used straight out of the pack, though a full charge is recommended for optimal initial performance.
What is the difference between these and alkaline batteries?
These are rechargeable NiMH batteries designed for reuse, whereas alkaline batteries are single-use disposables.
Troubleshooting
Battery does not hold a charge after long storage
While these feature low self-discharge, perform a full 'refresh' cycle if the charger supports it, or simply perform a full discharge and recharge to recalibrate the chemistry.
Device operates intermittently
Ensure the battery contacts in both the device and the battery itself are free from corrosion or debris; wipe with a clean, dry cloth.
Charger indicates an error
Confirm that the charger is compatible with NiMH technology and that the batteries are seated firmly in the charging slots.
Pros and Cons
Pros
- Retains charge effectively during long periods of inactivity
- Environmentally friendly alternative to single-use disposables
- Compatible with standard rapid chargers
- Suitable for a wide range of standard electronic applications
Cons
- Lower nominal voltage (1.2V) compared to 1.5V alkaline batteries
- Requires an initial investment in a charging unit
- Not intended for industrial high-drain specialized equipment
Setup, Compatibility & Care
To ensure maximum lifespan, charge your Varta batteries fully before their first use. Since these are NiMH batteries, they do not require a special proprietary charger; any standard NiMH-compatible rapid charger will suffice.
Care Tips:
- Avoid exposing the batteries to extreme moisture or temperatures exceeding 50°C.
- Do not mix these rechargeable batteries with standard alkaline or zinc-carbon batteries in the same device.
- Remove batteries from devices that will be left unused for extended periods to prevent potential leakage or slow self-discharge.
- Ensure contacts are kept clean and free of dust for optimal energy transfer.
